70% to pass

When tank cleaning with a portable machine, the weight of the machine is suspended from _______________.

A solid iron bars clamped to the Butterworth opening
B the suspension line, usually manila or natural fiber line
C a wire rope suspension line
D the supply hose
AI Explanation

The correct answer is D) the supply hose. When using a portable tank cleaning machine, the weight of the machine is suspended from the supply hose, not from solid iron bars, a suspension line, or the Butterworth opening. The supply hose provides the necessary support and connection to the cleaning machine, allowing it to be maneuvered and positioned within the tank being cleaned. The other options are incorrect because they do not accurately describe the standard configuration and operation of a portable tank cleaning machine. Solid iron bars, suspension lines, and the Butterworth opening are not used to support the weight of the machine during tank cleaning operations.
